Spatially constrained scanning scheme applied for gap measurements Article (Web of Science)

abstract

  • PurposeThe purpose of this paper is to investigate an optical‐based scanning modality for the real‐time measurements of automotive interior gaps.Design/methodology/approachThe hardware is based on a charge‐coupled device detector acquiring a laser illumination. The laser is projected on multitude of substrates with different reflectivities and surface profiles; while the scanning is progressed manually through a hand‐held setup.FindingsThe proposed software identifies the optical gap location automatically and establishes a dynamic field of view.Research limitations/implicationsThe study conducts a tool reliability and repeatability study that yield an accuracy of 0.08 mm and a repeatability of less than 6.5 percent as user bias. The developed hardware/software combination, when compared with two commercial systems; a 3D scanner and an industrially packaged sensor unit used for exterior gaps, which provided repeatability values of 24 and 17 percent, respectively, with accuracies of 1.5 and 0.34 mm.Originality/valueNew hardware and software are developed in combination to operate effectively on different deco finish and gap separations.
